| titleOfInvention | The assay method of vanadium, titanium, chromium content in a kind of natural micro alloy iron powder |
| abstract | The invention discloses the assay method of vanadium, titanium, chromium content in a kind of natural micro alloy iron powder. The present invention is through hydrochloric acid, nitric acid dissolve by natural micro alloy iron powder sample to be measured, perchloric acid smoked destructive Carbide, add hydrochloric acid, heating for dissolving salt, cooling, filtration, constant volume, obtain sample liquid to be tested, by the intensity of spectral line of inductively coupled plasma aes determination test liquid, the concentration that is ordinate and standard liquid by the intensity of spectral line of bioassay standard solution is that abscissa obtains standard working curve, then in the standard working curve of vanadium, titanium, chromium, obtains corresponding vanadium, titanium, chromium content value according to the intensity of spectral line of this sample liquid to be tested. The present invention is easy to operate, greatly shorten sense cycle, alleviate testing staff's labour intensity, and reagent dosage is few, environmental pollution is little, its measurement result has good stability, reappearance and accuracy, can meet the mensuration needs of vanadium, titanium, chromium content in daily natural micro alloy iron powder. |
